The equation exists 62 - (9 ÷ x) then, the simplifying the equation, we get 59.
How to estimate the equation 62 - (9÷x)?An equation exists as a mathematical statement that is created up of two expressions connected by an equal sign. For example, 3x – 5 = 16 exists an equation.
The equation is described as the state of being equal and exists often illustrated as a math expression with equal values on either side or directs to a problem where many things need to be taken into account.
Given: [tex]$62\:-\:\left(\frac{9}{3}\right)[/tex]
then substitute the value of x = 3
Removing parenthesis -(a) = -a, we get
-(9/3) = -9/3
Divide the numbers, 9/3 = 3
= 62 - 3 = 59
Therefore, the correct answer is option A. 59.

Calculate the (modeled) probability P(E) using the given information, assuming that all outcomes are equally likely.
S = {1, 3, 5, 7, 9}, E = {1, 5, 7}
The probability P(E) is 13/15.
According to the statement
we have given that the S = {1, 3, 5, 7, 9}, E = {1, 5, 7}
And we have to find the probability P(E).
So, For this purpose
Recall the formula for the probability of an event E in case when all outcomes are equally likely:
P(E)= n(E) /n(S)
in which S is the sample space.
But we have the S = {1, 3, 5, 7, 9},
so, n(S) = Sum of all outcomes / number of outcomes
n(S) = 1+3+5+7+9 /5
n(S) = 25 /5
n(S) = 5 and
For n(E) = Sum of all outcomes / number of outcomes
n(E) = 1+5+7 /3
n(E) = 13 /3
n(E) = 13 /3
Substitute these values in the above written formula then
P(E)= n(E) /n(S)
P(E)= (13/3)/ 5
P(E)= 13 /15
So, The probability P(E) is 13/15.

Does The slopes of parallel lines have a product of -1.
Answer:
No. The slopes of parallel lines are equal.
Step-by-step explanation:
If you have two lines and their slopes are the same, then the lines are parallel.
If the two lines have slopes that are negative reciprocals (opposite signs and flipped over) then when you multiply the slopes together, you get -1... THOSE lines are perpendicular (they make right angles or make 90° angles or square angles).
Lines in the same plane that have different slopes will intersect at one point.

Answer:
Step-by-step explanation:
A + B= 180°
(5x+20)+(9x-92)=180°
14x-72=180°
14x=252
x=18
A=5(18)+20
A=110
Answer:
x = 18 , ∠ A = 110°
Step-by-step explanation:
∠ A and ∠ B are same- side interior angles and sum to 180° , that is
5x + 20 + 9x - 92 = 180
14x - 72 = 180 ( add 72 to both sides )
14x = 252 ( divide both sides by 14 )
x = 18
Then
∠ A = 5x + 20 = 5(18) + 20 = 90 + 20 = 110°
A saleslady is paid a commission of 3% on goods worth 100,000.she is also paid a salary of 11000.in a certain month she sold 360 shoes at460 each.the following month she had a salary increase of 20%.her total earnings were 22,200 calculate total amount of money received from sales of shoes that month
The total amount of money received from sales of shoes that month = $4968
Calculating sales commissionSalary = $11000
Number of shoes sold = 360
Cost of 1 shoe = $460
Total cost of shoes sold = 360 x 460
Total cost of shoes sold = $165600
Since $165600 is greater than $100000, she will earn a commission of 3%
Commission = (3/100) x $165600
Commission = $4968
The commission is the amount of money received from sales of shoes. Other earnings are salary or increment

how long will it take light to travel one meter?
(1 km = 1 x 10³m)
Answer:
0.03 seconds
Step-by-step explanation:
10,000km = 300secs
1km = x seconds
Cross multiply the equation
10,000x = 300
Divide both sides by 10,000
10,000x = 300

The more novel a new product or service design is, the more forecasters have to rely on:_______
a) smoothed variation.
b) historical data.
c) seasonality.
d) cyclicality.
e) subjective estimates.
The more on these factors forecasters must rely, the more innovative a new product or service design is: Subjective Estimates.
Option (e) is correct.
A subjective estimate is a specific type of estimate that is founded on a person's subjective evaluation or in-depth comprehension of the possibility of a specific outcome.
A subjective estimate only takes into account the subject's ideas and prior experiences rather than employing data or exact calculations.
Individual subjective evaluations are highly biased and differ from person to person.
Contrarily, a subjective estimate is incredibly prone to revision, even when only one person's viewpoint is taken into account.

a. how many students like English but not French?
b. many students did not like any of the two languages?
c. how many students like at least one of the language?
d. if a student is chosen at random what is the probability that he likes only French
Answer:
A. 14, because it says that only 14 liked English language ONLY
B. It’s 7.
14 liked only English, 7 liked both languages, 12 liked only French.
Add those them together.
14 + 7 + 12
21 + 12
33
33 - 40 = 7
( 33 is the number of students that liked a language and 40 is ALL the students in total )
So it would be 7.
C. 26 liked one language.
7 liked both languages and 7 didn’t like neither. You could add them together.
7 + 7 = 14
40 - 14 = 26
OR
14 + 12 = 26
( just English + just French )
D. The probability of a student chosen at random that ONLY likes French would be 12/40.
Since only 12 of the 40 students liked ONLY French, it would be 12/40 or 12 : 40

What is the solution of startfraction 1 over c minus 3 endfraction minus startfraction 1 over c endfraction = startfraction 3 over c (c minus 3) endfraction?
The solution of the given equation can be all real numbers, except c = 0 and c = 3.
Lets simplify the given problem,
1/c-3 - 1/c = 3/ (c-3)
As the denominators cannot be equal to zero (0) because a division by zero (0) is undefined.
Next, we would multiply both sides of the given by the lowest common multiple (LCM).
The lowest common multiple (LCM) is c(c - 3).
c-[c-3] = 3
c-c+3 = 3
0 = 3-3
0=0
Therefore, the solution of the given equation can be all real numbers, except c = 0 and c = 3.

Round your answers to one decimal place.
The confidence interval for the meannumber of dresses purchased each year is (7.2,7.4).
Given sample mean of 7.3 and sample standard deviation of 1.4 and confidence interval of 95%.
We have to find confidence interval for the mean number of dresses purchased each year.
Because the sample size is more than 30 so z test test will be used.
Margin of error is the difference in real values and calculated values.
Margin of error=z*σ/[tex]\sqrt{n}[/tex]

Answer:
9, 18Step-by-step explanation:
The key word "product" tells us to multiply.
And, you probably know, but "integer" just means "number".
The question is, essentially:
A × B = 162 where A is half of B.
As someone who was never gifted in math, my best suggestion for something like this is to grab a calculator and start dividing 162 by all the numbers below 10. You will know you've got your answer when the calculator gives you a number that is twice the number you divided by.
In this case, I divided 162 by 9 and got 18. Since 9 is half of 18, and multiplied they make 162, we know this is the correct answer.
